Specification of Letters Patent.

Patented Dec. 8, 1914.

Application filed August 29, 1912. Serial No. 717,740.

To all whom it may concern Be it known that 1, LE ROY K. VAN HORN, acitizen of the United States, residing at Youngstown, in the county ofMahoning and State of Ohio, have invented certain new and usefulImprovements in Molds for Making Concrete Structures, of which thefollowing is a specification.

My invention relates to molds for cement or concrete walls, andparticularly to detachalole, adjustable molds.

The object of this invention is to provide means of this character forforming cement walls, beams, columns, piers, sea walls, etc., of uniformor varying thickness, or any regular geometric shape, and having plane,offset, or beaded surfaces.

Another object is to provide a structure of this kind for formingceilings, girders and floors.

An important object is to provide a structure of this character which iscomposed of plane sections, adjustable angle and corner sections, andcurved sections cooperating with fillers which are all easily detachablefrom the molded wall.

Another important object is to provide sections of varying lengthscotiperating with adjustable corner sections, in order that the moldsmay be adjustable to a very small degreeg1 for forming walls of anylength desire A further object is to provide eflicient and simple meansfor spacing and securing the two walls of the molda Still another objectis to provide means for quickly and easily attaching together thedifferent plates which form the walls of the mold.

With these and other obiects in view my invention consist. in the novelarrangement and combination of parts as more fully set forth in thefollowing description and claims.

Referring to the drawings forming a part of this SQGClfiRLLLlOH and inwhich like numerals are used to designate corresponding parts throughoutthe several views: Figure 1 is a perspective view of my mold for forminga plane, straight wall, Fig. 2 is a perspective view of an angle plate,Fig. 3 is a horizontal section of an angle mold, Fig. 4 is a perspectiveview of a filler used in constructing an angle, Fig. 5 is a perspectiveview of a box or corner filler used in constructing ceilings, Fig. 6 isan end view of the mold as arranged for forming a wall of uniformthickness, Fig. 7 is an end view of the mold as arranged for forming awall tapering toward the top, Fig. 7 is a detail view of a tie-rod, Fig.8 is a fragmentary perspective view of a modified form of plate, Fig. 9is a perspective view of a plane and angular mold formed of thismodified form of plate, and a section of wall molded thereby, Fig. 10 isa perspective view of various plates arranged to form a wall, a ceilingand girder in one operation, Figs. 11, 12 and 13 are perspective viewsof securing bars for holding the plates in ceiling construction, Fig. 14is a perspective view of plates arranged to form a wall, cornice andpitched roof in one operation, Fig. 15 is a perspective view of platesarranged to form a girder, Fig. 16 is a horizontal section through planeand curved plates arranged to form a column projecting from a wall, Fig.17 is a perspective view of two of the curved plates provided withofi'set portions for receiving secondary molds for ornamentation, Fig.18 is a detail section through the union of two such plates, Fig. 19 isa perspective view of a fragment of a wall mold provided withreinforcing supports, Fig. 20 is a perspective view of a clamp forholding the hooks and staples of contiguous plates from displacement,and Fig. 21 is a sectional view of a wall showing means for removing hetubes.

Referring more particularly to the drawings, the numeral 1 designates afiat plate preferably of iron or steel, and of any desired size, exceptthat it should be a multiple of any desired unit. These plates areprovided along one side and one edge with angular hooks 2, and along theother side and edge with rectangular sockets 3. The hooks and sockets onadjacent plates are to co operate with each other as shown. If de sired,these hooks and sockets, after being placed in engagement, may be lockedtogether by means of the locking member 4, as shown in Fig. 21. Theplates 1 are also provided with openings 5, to receive tie-rods 6 whichpass through the tubular spacing elements 7 disposed between the outerand inner plates of the mold, and abutting a ainst the inner opposingfaces of the same. hese tie-rods comprise a head 8, formed tubular forthe reception of a bar or the like for removing the rod from the wallwhen molded, and an extended body portion 9 provided by their use, thelength of a wall may be varied to as small a degree as one inch. Thecorner or angle sections are applied to the outside and inside of theouter and inner walls of the straight mold as shown, and are merelyplates preferably bent to any desired fixed angle. The corner sections12 have openings 13 in their two angular sides for the reception of thehooks 2 on the edges of the plates 1 and are also provided with openings14 for the reception of the tie-rods 6, and a series of openings 15 fora purpose to be described. In order that these corner sections will molda wall having a smooth surface, I provide fillers 16 contacting with theinside and outside of the outer and inner angle plates, respectively, asshown clearly in Fig. 3. These fillers are composed of a series offiller plates, as shown in detail in Fig. 4. The filler comprises anangular plate 17, and a series of plates 18 and 19. The plates 18 and 19may be of any desired width, but it is preferable to form all plates themultiple of a certain unit for purposes of ad ustment.

The purpose in having the fillers in sections is to enable a corner tobe properly filled so that the Walls of the mold will be flush,regardless of whether a short angular filler plate, or a more extendedfiller is required.

In order to secure the filler plates to the angle or corner plates, Iprovide them with a series of openings 20 adapted to register with theopenings 15 in the corner or angle plates, and adapted to receiveclamping bolts 21. It will be noted that one of the openings 20 isdisposed at the edge of each filler plate, so that the wide fiat heads22 of 'the bolts will overlap the union of each contiguous plate, andthus hold them in place. The filler plates are further provided withapertures 23 for receiving the tie-rods for holding the forms to ether.

In Figs. 8 and 9 have shown the same general construction of mold,except that the plates, angles and fillers are provided with effectportions 24. These plates are adapted to'form a stepped wall. Bysecuring molding 25 of any desired design within these ofiset portions24, it is possible to form a wall having ornamental beading or cally inthe Wall mold, and horizontally in molding upon its surface, as shown at26. It will be understood that the tie openings will have to extendthrough the molding.

In Fig. 10 I have shown an arrangement of plates, angles. and fillersfor forming walls, a ceiling, and a girder in one operation. 2'?indicates awall mold, 28 the ceiling mold, and 29 a girder mold. Theplates 1, angles 12 and fillers 16 are arranged vertithe ceiling andgirder mold 28, as shown.

In order to form the inner corners of the ceiling, I provide cornerboxes 30 illustrated in detail in Fig. 5, which are bolted in place bymeans of securing braces 31, 32 and 33. These securing braces areprovided with bolt receiving apertures 34, and tie receiving openings35. Of course,iin this instance it will be necessary to support thismold structure, For this purpose I employ arrangement of planks 36, andupright posts or supports 37.

In Figs. 14 and 15 I have shown my molds adapted for girderconstruction, to be used in connection with a wall or ceiling, orseparately. In this instance itwill be noticed that scafioldingcomprising horizontal planks 38 and vertical posts 39 is required tomaintain the mold in its elevated position. These girder moldscompriseplane plates or plates either angular or plane. provided with offsets 40secured in end to end relation, spaced apart by the tubes 7 and clampedby means of the tierods 6. Within the oifsets 40 moldings 41 of anydesired shape may be bolted as at 42 for ornamental effect. In order tosup-port the angular plates a brace 43 may be pro vided having thereinan aperture 44 for the reception of a tie-rod 6.

In Figs. 16 to 18, I have illustrated my mold structure adapted to molda column either connected with or separate from a wall. This structurecomprises curved plates 45 .having straight portions 46 extendingtherefrom for connection with the plane plates 1. The portions 46 are'ofthe same construction ,as each leg of the angle plates, and are providedwith openings 47 for the reception of bolts '48, having flattened wideheads 49, by means of which the filler plates 16 are secured. The curvedplates 45 are also provided with hooks and staples ,of the same as onthe plane plates, lVhen it is desired to bring two of the curved platesclosely together, I provide a bar 50 between them, which may be of anydesired thickness. A bolt passes through the portion 46 of the platesand the bar 50, thus holding them securely together. In order to preventaccidental turning of this bolt, a rivet or pin 52 is inserted within anopening through the bar 50 and the bolt 51 as shown. These curved plates45 may be formed with offsets 53 within which mold- 130 1,1eo,ece

ing 54 may be secured by means of bolts 55, for forming ornamental basesfor colmuns.

In very heavy work it is sometimes deseirable to strengthen the walls ofthe mold. With this end in view, I provide a reinforcing meansillustrated in Fig. 19. This re inforcement consists of a series ofcrosses or spiders 56 disposed upon each of the tierods 6, with theextremities of their arms abutting against each other as shown at 57.Each cross or spider is provided with an opening 58 at the junction ofits arms for recei ing the tie-rod.

After the cement has been poured into the molds, and set or hardened,the wedges are removed from the tie-rods, the tie-rods are withdrawn,and the plates are removed. It will be noted that the spacing tubes 7will then remain in the wall. In order to remove these tubes I provide adevice illustrated in Fi 21, comprising a cylindrical portion 59 ot thesame diameter of the tube, and having a reduced end 60 which is adaptedto be inserted within the tube. It will be readily seen that the blowupon this device will cause the shoulder 61 to force the tube out of thewall.
